JAMES ,TENDER Fon Lo'oomorlves.'

Be it .known that I, WILLIAM PETER l SOHERER, a citizen of the `Unitedi'States,l residing at Bulf-alo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Tenders for Locomotives,` of which kthe following is a specification.

. the coal-supply withinv convenientv reach of This invention relates toa locomotive-tender in which means are provided for shifting the coal in the coal-space forward toward the cab of the ylocomotive asit is'used, so that it may be conveniently reached by The main obj ect of the invention is 'to facilitate thev operation of firing by maintaining the fireman in the cab.

In the specific adaptation of the invention illustrated in the accompanying drawings the coal-space is provided with a false or movable'wall which is moved forward byA fluidpressure to force the coal toward the forward end of the tender. The supply of com ressedfluid is controlled by a valve device -ocated within convenient reach ofthe iireman or engineer.

' The adaptation of' the invention shown also relates to certain details of construction,

the movable wall on line b t, Fig.' 1.

all of which will be fully and clearly hereinafter described and claimed ,reference being had to the accompanyin drawings, in which- Y Figure 1 is atop p an view of the improved 1 tender coupled -to alocomotive.

manner. to the locomotivel and has the usual lwater compartment or space 4,' trucks 5, and coal-'space r6. .The coal-space has vertical lside walls 7 and' a slanting or diagonal rear jwall 8, which terminates near the top of the tender in a short .transverse wall 9. A movwall and is composed oftwo members', which are connected so. that they may be moved v relatively to each other to widen or narrow the wall.. The upper memberhas a vertical top plate 10 and a lower plate 11, hinged in :said to prefera lyA a single plate and partially laps and slides upon the lower plate l1 1, being provided with slots 13,' through-which projec- =tions 14 from the lower plate 11 are slidably fitted to adjustably secure the twomembers together. The lower member is moved upon Vthe upper member to widen the movable wall by fluid-pressure mechanism, as will be more vclearly hereinafter set forth. The movable wall is supported from the side walls 7 of the 'coal-space so that it willbe moved forward :and back in an approximately horizontal dilrection by horizontal ledges 15,' secured to tlie side walls near the to` thereof, which project into recesses 16 in t e topfportion 10 of the upper member.

The fluid-pressure mechanism for shifting the movable wall comprises one or more aircylinders 1 7, preferably two, which are mounted horizontally and-longitudinally upon the tender-top in the rear of the coal-space. A

double-action piston 18 is I'itted in each of' plate,v and the lower member 12'isvthe air-cylinders, when more than one isemployed, so as to reciprocate therein,`and ismounted upon the inner 4end of a hollow piston-rod 19. The piston-rods 19 in the double-cylinder construction .illustrated in the accompanying drawings arel eachl -connected at their forward ends to the movable wall, so that reciprocation of the piston and its rod will likewise move the movable wall.

- The lower member is moved downward Vupon vthe upper member of the movable wall by fluid-pressure, an air-cylinder 20 being mountedupon the upper member-and connected at its up er end to the` ends ofthe "hollow piston-ro s 19 by pipes 21 vand 22, the pipe 21 connecting Vthe ends of the pistonrods and -the pipe 22 extending from approximately the middle of the pipe 21v and connecting to the cylinder. A piston 23 in the cylinder 20 has a rod 24 connected to the lower member and is but single-acting, the lower member being automatically returned to its upper position by a spring 25, located within the cylinder, the tension of which retracts the piston.

The cylinders 17 are connected at each end to a source of fluid-pressure supply, preferably to the main air-reservoir2 on thejlocomotive, by separate pipes 27 and 28, each of which has shut-off valves 29 and 30, and extend within convenient proximity of the engineer or fireman in the locomotive-cab. The pipe 27 for forcing the movable wall forward will hereinafter be termed the forward-force supply-pipe and the pipe 28 for returning the wall to its position in proximity to the ermanent rear wall of the coal-space will be ereinafter termed the i return-force supplypipe. Each of the pipes 27 and 28 are connected by branch pipes 31 to both cylinders for simultaneous operation.

The coal-space may be rovided with wings4 32, which extend above t e side walls thereof and serve to provide additional space, so that the coal-space may be filled heaping full without danger of the coal running over the sides. These wings 32 are pivoted to the vertical plate 10 of the movable wall, so that they may be turned back out of the way when not in use.

The operation of the device is as follows: The coal pile having been used sufliciently in front to render it inconvenient for the fireman to shovel, the valve 29 is opened, which permits the'compressed air from the main air-reservoir to press against the pistons 18, forcing them forward and by means of the connecting piston-rods sliding the movable wall forward and pushing the coal to within convenient reach of the fireman. At the same time the compressed air passes through the hollow piston and the connecting-pipes 21 and 22into the cylinder 20, forcing the piston out and sliding the lower member u on the upper member to widen the wall. lhe

' length of movement of the movable wall is easily regulated by the air-valve 29, and the wall can be moved forward from time to time until the coal in the coal-space is entirely used.

The construction of the mechanism may be varied or changed without departing from my invention, which comprehends the moving of the coal in the coal-space toward the cab as it is used, so that the fireman will always have a supply of coal within convenient reach.

While I have shown a multipart construction of movable wall, it may be infone piece andv may be shifted in various ways to move the coal toward the cab as it is used.
